Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth's density is grams per cubic centimetre.

 · Gravel size crushed rock is a desirable material for buried pipe support. However, large scale tests to measure strength properties of gravel particles are impractical because of the expense and lack of standard procedures for cohesionless soils. Thus, only presumptive values of the constrained modulus (Ms) for crushed rock are available.

compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. The size dependancy is also found to exist for stiff …

The safe bearing capacity of soil should be determined on the basis of soil test data or by performing some field test such as Standard penetration test or Plate load test etc. However, in the absence of soil test data, the values of safe bearing capacity () as given in the following table may be used as a guide for preliminary analysis.

Granite (gravel) crushed stone is the most demanded and popular. The bulk specific gravity is g / cm3. Fraction of granite crushed stone up to 5 mm refers to crushed stone screening. It, in turn, contains an increased amount of dust and sand residues - much more than the two percent specified in the GOST standards.
